CyanogenMod 9 may still be a ways out, lending some credence to the claim that upgrading from Gingerbread to ICS is a very long endeavor. However, if you're willing to live your life on the bleeding edge, and you own an international Galaxy S III variant, then the time is right for you: CM9 nightlies are now available for your device.
This is, of course, still an early build, so expect some bugs along the way. CM9 has still not reached release candidate stage yet, which is itself still a few steps away from stable release. The adventurous and the knowledgeable need not concern themselves, though.

If you're on the regional carrier C Spire and have been jealous of all the Galaxy S III banter, you can lay that jealousy to rest. C Spire just announced that it will be getting the Galaxy S III as one of the initial devices to run on its upcoming 4G LTE network.
The device will launch with identical specs to the other U.S. carriers:
4.8" Super AMOLED HD display with Gorilla Glass 2.0
1.5GHz dual-core Snapdragon S4
16GB on-board storage with microSD card slot
Android 4.0 with TouchWiz
Unfortunately, pricing and release date information aren't yet available, but the company plans to launch its LTE network in 20 Mississippi markets beginning in September, and the GSIII will most likely be its flagship for the launch.
